Clinico-physiological status of Thai COPD patients.
We examined the relationships between certain clinical and physiological data from 56 patients with chronic obstructive pulmonary disease, and have formulated 15 relevant equations from which various respiratory indices can be estimated. Multiple linear regressions thus obtained evidently suggest that airway resistance and ventilatory drive are the main factors in the control of breathing among Thai COPD subjects; the exercise tolerance test showed some correlation with airflow obstruction and with respiratory muscle strength. Clinical implementation of certain findings has been outlined.
